1. In an eyeglass mounting, tion with'an arched bridging portion and alens attaching portion separate therefrom, of a separable fastenerconnecting theparts together and a nose guard pivotally mounted on thelens attaching portion, independ- Y ently of such connection, at a.point in the plane .ofthe lens between the arch of the bridging portionand the lens comprising a i lever movable relatively to both parts andhaving a finger piece at its forward end and a'nose engaging portion atits rear end.

2. Inan eyeglass mounting, the combina- I tion with a lens attachingportion provided with av box and an archedbridging portion having itsend cooperating with the box, of a separable fastener connecting thebridge end and the box and a nose guard pivotally mounted on the lensattaching portion, independently of such connection, at a oint in the'lane of the lens between the arc of the bri ging portion and the lenscomprising a lever movable relatively to both parte and having a fingerpiece at its forward endend a nose engaging portion at its rear end.

3. In an 'eyeglass mounting, the combination-with a lens attachingportion and an arched bridging portion separate therefrom, of aseparable fastener for connecting said arts, apost on the lens attachingportion ormed integrally therewith and arranged at a point between'thearch of the bridging portion and the lens, and a nose guard pivoted onthe post.

of a threaded fastener connecting the partstogether and' extendinghorizontally, a second vertically extending fastener carried on the lensattaching portion in the plane of the lenses between the arch of thebridge and the adjacent lens and connected to the lens attaching portionindependently of the connection between the latter and the bridge, and--a pivoted finger piece nose guard secured by said last mentionedfastener.

5. In an eyeglass mounting, the combination with a lens attachingportion and a bridging portion separate therefrom, of a fastenerconnecting said parts together and extending into the lens attachingportion, a

ost on the latter .lying transversely of the astener, a second headedfastener secured in the post and a nose guard turning on the ost at apoint intermediate the head of such astener and the lens attachingportion.

6. In an eyeglass mounting, the combination with a lens attachingportion and a bridging portion separate therefrom, of a fastenerconnecting said parts together and extending horizontally into the lensattaching portion in the plane of the lenses, a verticallyextending'post on the lens attaching portion, a headed fastener securedin the post and a nose guard turning on the latter at apointintermediate the head of such fastener and the lens attachingportion.
